To all whom it may concern: thebolts after the properbalance isobtained.

Be it known that we, JOHN F. MEIGs, a The slot 1 is open at one end ofthe case and citizen of the United States, residing at communicates withan opening 8 in that end South Bethlehem, and HERMAN G. JAKoBsto permitthe case to be withdrawn without 5 SON, a subject of the King of Sweden,residwholly removing the bolts, and the case is ing at Bethlehem, in thecounty of Northopen at the inner side to permit the insertion ampton,State of Pennsylvania, have inventand removal of the weights 5 betweenthe cd certain new and useful Improvements in partitions 6, and when thecase is in place a Adjustable Balancing-VVeights, of which the pendentflange 9 of the frame retains the 10 following is a specification.weight within the case.

This invention relates to an improvement In the construction shown inFigs. 4 and 5 in ordnance, and has for its object to change there is asingle weight 10, which conforms at the balance of any gun pivotallymounted to its upper part to the outer form of the recoil- 6o swingvertically; and it consists in providing cylinders E E, and this weight,which is car- I 5 the gun or its attachments with a support ried on athreaded sleeve N, is movable upon for a weight adjustable thereon, asfully set the support, which is in the form of a screwforth hereinafterand as illustrated in the acshaft F, turning in said sleeve and inbearcompanying drawings, in which ings 12 of the cradle and limited inits niove- Figure 1 is a side elevation of a gun and its mentlongitudinally by a head 13 and nut 14,

Fig. 2 the latterbeing restrainedfrom turning by a is a plan of Fig. 1; Fig. 3, a section on thecross-pin 15, so that the shaft F may be line 3 3, Fig. 1; Fig. 4, aside elevation of a turned in the sleeve N by the application of agun-saddle, showing another form in which wrench to the nut 14 and theposition of the our invention may be embodied; Fig. 5, a weight therebyadjusted longitudinally in re- 25 section on the line 5 5, Fig. 4. spectto the pivots of the gun.

In the construction shown in Figs. 1 and 3 By providing the gun with abalancing the gun is mounted upon the cradle B, proweight or weights, asdescribed, a prepondervided with the usual trunnions 7, although in anceof weight at the breech or the muzzle carrying out our invention thetrunnions and to any varying extent required may be 30 may be upon thegun itself. Connected with secured to adapt the manipulation of the thegun or its attachments, whatever the latgun to the personal equation ofthe person ter may be, there is a support F, which, as using the same inthe case of smaller arms, shown in Figs. 1 to 3, is a flange, the saidwhile with guns of larger caliber, where the support being the means ofsupporting adelevating is done through the medium of 3 5 justably abalanced weight or weights the pogearing and where the balance varies inacsition of which in respect to the trunnions decordance with theelevation of the gun in tel-mines the extend to which the gun is balconsequence of attachments connected thereanced 0r overbalanced upon itspivots, on with-as, for instance, shields carried by the which it swingsvertically. gunthe weight may be adjusted so as to 40 In theconstruction of Figs. 1 to 3 there is a properly balance the gun when itis in its difseries of weights 5 within a case A, bolted to ferentpositions for firing. The adjustable the support F by means of bolts C,which ex weight also permits of the change of balance tend through theflange or support F and required when in target practice. A small- 0through a longitudinal slot 1 in the top of the caliber auxiliary barrelis inserted in the gun 45 case A, permitting the latter to be shifted inplace of the charge. By use of the ballongitudinally to change thebalance and to ance-weight also the assembling and mountbe secured inposition by turning the nuts of ing of the parts of the gun may befacilitated lll llll in 'i by approximately locating the center of thetrunnions without balancing and compensating for any irregularity byadjustment of the weight, so as to avoid the necessity of balancing eachgun and cradle together in order to locate the center of trunnions onthe cradle.

Without limiting ourselves to balance means and shiftin appliances ofany special construction, we 0 aim 1. The combination with a gun pivotedto swing in a vertical plane, of balancing means adjustable to differentpositions relative to the pivot of the gun, substantially as described.

The combination with a gun mounted to swing ontrunnions, of a weight, a support for said weight, and means wherebysaid weight may be shifted and retained on said support in differentpositions in respect to the gun,
